The shape of clouds has proven to be essential for classifying them. Our analysis images from fair weather cumulus reveals that, in addition turbulence, they are driven by self-organized criticality. observations yield exponents that support the fact clouds, when projected two dimensions, exhibit conformal symmetry compatible with $c=\ensuremath{-}2$ field theory. By using a combination Navier-...

Self-organized criticality (SOC) refers to the ability of complex systems evolve toward a second-order phase transition at which interactions between system components lead scale-invariant events that are beneficial for performance. For last two decades, considerable experimental evidence has accumulated mammalian cortex with its diversity in cell types, interconnectivity, and plasticity might ...

Abstract Power-law size distributions are the hallmarks of nonlinear energy dissipation processes governed by self-organized criticality (SOC). Here we analyze 75 data sets stellar flare distributions, mostly obtained from Extreme-Ultraviolet Explorer and Kepler mission. We aim to answer following questions for flares. (i) What values uncertainties power-law slopes? (ii) Do slopes vary with tim...

Significance Termite nests are a remarkable example of functional self-organization that show how structure and function emerge on multiple length time scales in ecophysiology. To understand the process by which this arises, we document labyrinthine architecture within subterranean African termite Apicotermes lamani develop simple mathematical model relies physical biological interactions betwe...
